Updating the Firmware on Cisco UCS C-Series Servers

Upgrading the
Firmware on a Cisco UCS C-Series Server Using the HUU

You can use the HUU ISO to upgrade components of the server from the
host locally with a writable disk (DVD or CD), or remotely by mounting the HUU
ISO as a virtual device. This following procedure explains how to upgrade the
firmware using the HUU:

After the HUU boots, Cisco End User License Agreement (EULA)
appears, read the EULA and click:

I
Agree to agree with the license agreement and proceed with the
update.

I
Disagree to cancel.

After you accept the EULA, when the
Cisco Host Upgrade Utility window appears with
a list of all the components that are available for update.

Step 7

If you want to update all the listed components, click
Update all.

Step 8

If you want update specific components from the list, choose the
components that you want to update.

Step 9

Click
Update.

Note

We recommend you update the firmware on all components using
the
Update all option, unless you want to
specifically update the firmware of a component.

We recommend that
you update the BIOS each time that you update the CIMC firmware. We also
recommend that you update the CIMC each time that you update the BIOS firmware.

If you update the
CIMC
firmware, after successfully completion of the update, reboot the server to
activate the new firmware.

This initiates the update and the status of the update is
displayed in the
Update Status column. You can also view a
more detailed log of a series of activities and statuses that are involved
while updating the firmware in the
Execution Logs section.

Step 10

Reboot the server.

Step 11

Reboot the server, and click
Last Update Verify to verify if the update
was successfully completed.

This action compares the previously updated firmware version for
each component that was updated using the HUU with the current version of the
firmware on the components and provides the status of the update.

Step 12

If you want to save the log files of the update status for later
use, click
Save Logs.

Log files that contain a detailed status of the update are saved
to an external USB device that is connected to the server physically or through
the KVM vMedia.

Note

If an error occurs while updating the firmware, you are prompted
to save the error log. Click
Save Logs to save the log to an externally
connected USB. This log can be used for identifying the cause of the error and
troubleshooting.

Step 13

Click
Exit to exit from the HUU.

Note

If you have updated
the
CIMC
and not the BIOS, when you click
Exit,
CIMC
gets activated and you lose connectivity to the
CIMC
and KVM.

If you have selected
LOM for update and you are on shared LOM mode, when you click
Exit, you lose connectivity to the
CIMC
and KVM.
